eufy S1 Pro vs Dreame L40 Ultra

The Dreame L40 Ultra and the eufy S1 Pro are feature-rich flagship robot vacuums with mopping capabilities. Each features a robust real-time obstacle avoidance system and a multifunction dock for emptying the vacuum's dustbin, refilling the vacuum's internal water tank, and washing and drying mops. However, only the Dreame base station uses hot water to wash the mops. As far as performance goes, it's a toss-up. The Dreame is the better choice for people who have carpeting in their homes, and it does a better job of clearing debris overall. By contrast, if you have bare surfaces, get the eufy, as it delivers vastly better pick-up performance on this surface type.
